Níveis de dano e de controle do percevejo-verde-da-soja Nezara viridula (Hemiptera: Pentatomidae) em feijão-caupi

Abstract: Resumo: Estudos sobre níveis de danos causados por insetos são importantes para tomada de decisão de controle de pragas nas culturas e implementação de práticas de manejo integrado de pragas. Em culturas como as de soja e feijão-comum, esses níveis já foram estudados e definidos, e o manejo de suas pragas já está estabelecido. Entretanto, no feijão-caupi, que possui muitas pragas semelhantes às da soja e do feijão-comum, parâmetros utilizados para tomada de decisão de controle ainda precisam ser estabelecidos.… Show more

“…This way, a selection must be made for summer cultivation and another for winter cultivation, as it is already done in crops of maize, for example, in Paraná state (Zucareli et al, 2013). In the case of organic summer cultivation, it is worth noting that at the end of the crop cycle there was an intense attack of stink bug (Nezara viridula) on quinoa fruits, so that its yield was compromised, a condition already verified in other crops (Lourenção et al, 2010;Silva & Sobrinho, 2017), not being different with quinoa. Two applications of Neem oil were performed as an attempt to reduce the number of stink bugs in the area, but they were not efficient.…”
